I bought a H&R model 12 target last month at the OGCC show. Got it home and shot it a couple of days later and had quite a number of light firing pin strikes. I found out how to disassemble the bolt and saw the spring was broken. After looking all over I found out that Gun Parts had bought all the old H&R parts. I just recieved some new springs and found the old spring was 5/8's of an inch short, no wonder the light strikes. Hopefully I won't have any more light strikes.
